Transcriptomic phenotyping of human labor myometrium.

Project description:Myometrial biopsies were collected from 31 women undergoing primary cesarean sections and were carefully phenotyped with respect to gestational age (GA), circumstances of labor onset, and clinical status at the start and end of the intervention. Cases were aggregated into groups as follows: Group 1: term birth following spontaneous onset of term labor (TL, n=5); Group 2: term birth by elective cesarean section not in labor (TNL, n=5); Group 3: PTB following spontaneous preterm labor with intact membranes (n=6); Group 4: preterm birth following PPROM (n=8); and Group 5: provider-initiated preterm birth in the absence of active labor contractions, cervical dilation or membrane rupture (n=7). Additional phenotyping of cases spontaneously committed to PTBs (Groups 3 and 4) involved presence or absence of Triple I based on cultures of amniotic fluid obtained via clinically-indicated amniocentesis. RNAs were profiled using second generation RNA sequencing.

proteome of human myometrium landscape in labor and non-labor

Transcriptomes of human myometrium in labor reveals the increased molecular associated with inflammation under hypoxia stress

Project description:Labor involves a variety of coordinated events across physiological and biochemical aspects, the molecular mechanism responsible for the transition of the myometrium from the quiescent to a contractile state remains indistinct.The global transcriptome in human non-labor and in labor myometrium was investigated through RNA sequencing (RNA-seq) to explore biological processes and pathways alterations during labor. The transcriptomic bioinformatics results showed that the up-regulated mRNAs increased inflammation under hypoxia stress in laboring myometrium.

miRNA of human myometrium in labor

Project description:The maintenance of coordinated powerful episodic contractions of the uterus is the crucial factor for normal labor. The uterine contractility is gradually enhanced with the progression of labor, which is related to the gene expression of myometrium, competing endogenous RNA (ceRNA) can also regulate the gene expression. To better understand the role of ceRNA network in labor, transcriptome sequencing was performed on the myometrium of 17 parturients at different labor duration. Furthermore, an correlated analysis was performed to identify mRNA, long non-coding RNA (lncRNA), circular RNA (circRNA), and microRNA (miRNA) which correlated with their expression levels and labor duration. Then, targeting relationships between mRNAs, lncRNAs, circRNAs and miRNAs were predicted, and the ceRNA regulatory network was established.This analysis identified 934 RNAs positively correlated with labor duration (859 mRNAs, 28 lncRNAs, 45 circRNAs, and 2 miRNAs) and 153 RNAs negatively correlated with labor duration (122 mRNAs, 28 lncRNAs, and 3 miRNAs).

MeDIP assay using human myometrium of women with preterm labor of different phenotypes vs. normal term labor

Project description:Preterm birth is multifactorial in origin with several distinct clinical phenotypes of differing etiologies, including idiopathic preterm birth. Preterm birth involves the interaction of genetic, societal and environmental factors such as nutrition, lifestyle and stress that may modulate the length of gestation via the epigenome. DNA methylation is a well-studied epigenetic modification whereby promoter methylation commonly represses gene expression and vice versa. Myometrial tissue was obtained at cesarean section at term with or without labor, preterm without labor, idiopathic preterm labor, and twin gestations with labor. Differences in the myometrial epigenomes were identified at gene promoters, CpG islands, CpG island shores and shelves, gene bodies across the genome between the groups of women with preterm labor of different phenotypes vs. normal term labor. Functional clustering analysis indicated the significantly enriched pathways of hypomethylated genes (permissive) were related to acute inflammatory and acute-phase responses. By contrast, genes that are hypermethylated (repressive) revealed enrichment for contractile fibers and cell. This study provides the first high-resolution DNA methylome of human myometrium with evidence for differences in the methylome that may relate to idiopathic preterm birth via regulation of gene expression. The findings extend previous observations that idiopathic preterm labor is associated with subclinical intrauterine infection and inflammatory pathways and point to targets for further molecular characterization of preterm delivery.
